I am a bit confused. What are the major and minor differences between the a127 and e127? I believe they are both wifi enabled? I would like to think that I understand the following on the e127:

>NO module/sounder is needed for the fishfinder/sounder
>The B744V Transducer I have installed can be used
>The GPS antenna is built in?
>I can use an external GPS antenna?
>If the unit is built in I MUST use an external Raystar? Will a Raystar 125 (the one I am using with my classic C120) work?
> An 18" RAYDOME will connect directly to this unit?


MANY thanks for any input as I am ready to buy and retire my C120 Legacy system
Welcome to the Raymarine Forum Tony,

Q1. I am a bit confused. What are the major and minor differences between the a127 and e127?

Q2. I believe they are both wifi enabled? I would like to think that I understand the following on the e127:

A2a >NO module/sounder is needed for the fishfinder/sounder ... correct
A2b >The B744V Transducer I have installed can be used ... fishfinder transducers designed for use with the DSM300/DSM30/DSM250 may be adapted (w/E66066 Transducer Adapter) for use with an ax7/cx7/e7D/ex7/eSx7 MFD
A2c >The GPS antenna is built in? ... yes
A2d >I can use an external GPS antenna? ... yes. Both the e127 and a127 MFDs maybe interfaced to a Raystar 130 5Hz GPS Sensor. Alternatively, the a12x MFDs may be interfaced to a GA150 10Hz GPS Antenna.
A2e >If the unit is built in I MUST use an external Raystar? ... Should the MFD not be installed in a location affording it an unobstructed view of the skies overhead, then it may be necessary to interface the MFD to a Raystar 130 or GA150. Will a Raystar 125 (the one I am using with my classic C120) work? ... Yes.

MANY thanks for making me clear on the comparison! I will be replacing the Classic C system with an es. Thank you again Chuck!
You're welcome.
ONE more question, I am buying the e127 at the annual DEFENDER Warehouse sale. I will be using the B744V thru hull transducer. If I buy a redundant e97 unit also, can I network these together to utilize the same transducer or will I need a separate transducer? If a separate transducer needed, what model do I need? I am NOT an avid fisherman, just a guy who cruises in his 39' Carver. Thanks again!
Tony,

The a/c/e/eS/gS-Series MFDs are designed to be networked via Raymarine’s web site Ethernet networking to permit them to share all data and resources within the system except for NTSC/PAL video. As such, interfacing another a/c/e/eS/gS-Series MFD to the e127 MFD would indeed permit the e127 MFD to share fishfinder features with the other a/c/e/eS/gS-Series MFDs. As an additional ax7/cx7/ex7/eSx7 MFD's internal ClearPulse sounder circuitry would be redundant and not used, you may want to consider installation of an ax5/cx5/ex5/eSx5 MFD to save a bit of cost.
